We report a novel high-power bistable distributed feedback (DFB) semiconductor laser diode operating near 1060 nm, which is realized by inserting a high-bandgap electron barrier layer and a grating ...

We present our recent research on an OWPT network system for multiple acoustic emission (AE) sensors using 808 nm laser diodes (LDs) and silicon-based photovoltaic (PV) cells. A Bluetooth network was ...
